Cangzhou Sinhoo Pipeline can manufacture two types pipe reducer:concentric reducer(Con reducer),eccentric reducer(ecc reducer).We manufacture the products according to standard ANSI,ASME,API,BS,DIN,GOST etc.
The eccentric reducer is another kind of reducer which is different from the concentric reducer.As we know,the concentric reducer has two ends in same centerline,the two ends of eccentric reducer have one side in same level.So the shape of the eccentric reducer looks like |\.
Because of its shape,the eccentric reducer is always used in horizontal piping systems.For example,if you use a con reducer in the water draining piping,you have to tilt the pipe and reducer to get it to drain.Or you have to recalculate and arrange different pipe support systems when you use a concentric reducer to connect the two pipes.So the Horizontal piping reducers are always eccentric, they are better choice for bottom flat or top flat.
The shape of the concentric reducer like a / \, it is used a lot in the vertical piping systems.Because of the diameter change the pipes, it will bring the change in flow of fluid or other abrupt.When designing the piping system,the engineer should consider all the situation.If the system need to avoid the abrupt,the concentric reducer should be the first choice.The pressure will be even when the flow through the joint of a concentric reducer,it can make the piping stable.The shape of the concentric reducer is even,so it is easier to produce,the cost and price is lower comparing to the eccentric reducer.The butt welding reducer are made from the steel pipes directly for the common size.The bigger size more than 24 inches,will be manufactured from the steel plate.
In the butt welding pipe reducer market,the concentric reducer quantity is higher than the eccentric reducer.
The reason : 1. The price of the concentric reducer is cheaper than the eccentric one.
2.In the welding,the concentric reducer is easy to install,no need to consider the alignment.
